Well first you'd have to assess the reasoning behind GI bleeding before any recommendations on managing it. What is on the PT's MAR? Are they taking any anticoagulants, ASA, heparin, etc? All of which can cause an increased risk of GI bleeding What about pain meds? Are they taking advil long term? Advil can cause ulcers, which can cause GI bleeding. From there you can make a recommendation to switch to an alternate form of medication (if available) which is less prone to GI bleeding. For pain medication, typically that would include rotating between a few medications like acetaminophen and ibuprofen. Ibuprofen can cause ulcers, acetaminophen can cause cirrhosis or liver damage; so the key would be to rotate so no long term damage is done to either. In any case acetaminophen is much preferred just because NAC is available for OD. From there, I'd want to have bloodwork done to see what their platelet levels are like, or clotting factors, or anything else that might be relevant What about constapation or diarrhea? Do they suffer from either? How frequent is this GI bleeding? What signs/symptoms do they notice? If there's pain, can you isolate it to a specific region? All else fails, a CT scan would get a better understanding of the severity of the situation and potentially cause. MRI would be better, but it takes longer for results. I REAALLY can't give any kind of recommendation without SOME more information; medical history, symptoms, hereditary, bloodwork, allergies, pain level, pain location, etc etc. Anything would be helpful
